You’ve probably already seen that Alexandria Ocasio-Cortez rocked up at the Met Gala – where individual tickets are $35,000 (£20,000) and tables start at $200,000 (£150,000) – wearing a white dress saying in big red letters TAX THE RICH. It’s what the Clash called ‘turning rebellion into money’. Not one dollar in tax from the rich is going to be gained from this gesture — fashion can absorb anything and turn it into a trivial trend.
